Abstract: An ion implantation method and an ion implanter with a beam profiler are proposed in this invention. The method comprises setting scan conditions, detecting the ion beam profile, calculating the dose profile according to the detected ion beam profile and scan conditions, determining the displacement for ion implantation and implanting ions on a wafer surface. The ion implanter used the beam profiler to detect the ion beam profile, calculate dose profile and determine the displacement and used the displacement in ion implantation for optimizing, wherein the beam profiler comprises a body with ion channel and detection unit behind the ion channel in the body for beam profile detection. The beam profiler may be a 1-dimensional, 2-dimensional or angle beam profiler.
